' WATER-STILL.

Specificatin of Letters Patent. Patented Aug. 3 1, 1909.

Application filed June 1, 1909. Serial No. 499,488.

To all whom it may concern:

' Be it known that I, HENIEY J. BEHRENs, a

citizen of the United States, residing at \Yinona, in the county of\Vinona and State of Minnesota, have inventedcertain new and psefulImprovements in WVater- StiIls, of ,which the following is aspecification. v My'lnvention relates to certain new and usefulimprovements in water stills, and the object of my invention is toprovide a novel, simple, highly efficient and practicable water stillparticularly adapted for household purposes.

With these and other objects in view my invention consists in certainconstructions, combinaions and arrangements of parts the preferred formof which will be first described in connection with the accompanyingdrawings and then the invention particu- 'larly nted out in theappended. claims.

Re erring to the drawings wherein the same part is designated by thesame reference numeral wherever it occurs Figure 1 is a perspective viewof a still constructed in accordance with m invention and Fig. 2

' is a central longitudinal section of Fig.- 1.

The still, preferably, is constructed in circular form and composed .oftwo main parts 3 and 4, the latter seated on the former and readilydetachable therefrom. The lower part 3 is provided in its upper' portionwith a part 5 in the form of a truncated cone which is supported in theinterior of the part 3 by the flange 6 which extends from the lower edgeof the-cone to the side of the part 3. Preferably, and as shown, thepart 3 is provided with a spout 7 secured on its side and communicatingwith the interior 1 'of the part 3 by means of the opening 8 wherebywater to be distilled can be poured into the part 3, without removingthe upper 'part 4. The cone 5 andthe flange 6 divide the lower part 3into two sections, that portion above the flange and outside of the conebeing adapted to receive the distilled water as will be hereinafterdescribed. '9 is a faucet by means of which the water "can be drawn fromthe chamber above the flange 6 as desired. Located at the lower end ofthe' upper part 4 is a truncated cone 10 which extends fromsubstantially the -lower edge of the upper part 4- upwardly into thesame. 11 is a collar secured adjacent to the upper edge of the,cone andextending upwardly therefrom. Preferably,

and as shown, the lower edge of the collar boil.

is secured a short distancedown from the upper edge of the cone, wherebya ,shelf12 1s formed WhlCll 1s perforated as shown at 13 to permit watercondensed on the inner surface of the collar to flowdown throng-hsecured a collar 15 which surrounds thecone and extends upwardlytherefrom,

16 is a cone secured atiit's lower edge to the upper edge of the collar15 and extend ing over the collar 11. Extending fromthe apex of thiscone is a vent pipe 17.

18 is a faucet extending out through" the side of the upper part 4 .inorder to draw off the water containedthereinu.'. 19 is asection of pipeextending through the cone 10 and up into the lower edge the cone 14,whereby water contained ,i1 .the

the cone 16 Will'be drawn off into the section of the lower part 4 abovethe flange 6, as will be clearly SGGHTIOIIIFlg. 2.

In the operation of my still the lower por tion '3 is filled with waterto be distilled. Heat is applied and the Water brought to a 1e upperportion 4 is then filled with cooled water, said cool water surroundingthe exterior of the cone 10, extending up between the collar 11 and thecone l4 and covering the cone l6.- As the steam from the water containedin the lower part 3 rises it comes in contact with the cooled surfacesof the underside of the cone 10, condensesthereon and runs down the sideof the cone and drips into the portion of the lower part above theflange 6. The steam also condenses on the collar 11,runs downtheinterior thereof and passes through the opening 13 whence it runsdown the underside of the cone with thewater condensed upon the undersurface thereof. A portion of the steam also passes up into the cone 16Where it condenses and accumulates between the. collar 15 and the. cone'14, this water being drawn 01f by the pipe 19, through which it runsinto the receiving chamber inthe lower portion. When the water in thewpper portion becomes warm it can be drawn off through the spigot 18 andreplaced with cold water. The disspace between the cone 14,thecollar15-and tilled water can be drawn oil through the I s i ot 9 and thelower art filled b Y ourin a: l 3 P s 1 rendering interruption of theoperation unnecessary The pipe 17 is to prevent too great a pressurebeing produced in the still. in the ordinary action of the still nosteam escapes through this pipe, as the water which condenses thereinoperates as a sort of valve to prevent the escape of the steam.

l realize that considerable variation is possiblcdn the details ofconstruction and arrangement of parts Without departing from the spiritof my inventioinand I therefore do not intend to limit myself to thespecific form shown. and described.

' lilaving thus described my invention what I claim as new and desire tosecure by Let-- ters Patent is l. A water still comprising two parts onelocated above the other, a. truncated cone supported within the lowerpart and dividing the same into a lower chamber for the water to bedistilled, and an upper annular chamber adapted to contain' thedistilled water, a truncated cone-shaped part extending from the loweredge of the upper part, a collar extending upwardly from the innerportion of said truncated-cone, a second truncated-coneextendingoutwardly from the upper edge of said collar, a second collarsupported on the outer edge of said lastmentioned truncated cone, and acone extending from the-upper edge of said collar ineas est) closing thestructure within the second partof the still, said two truncated cones,said collars. and the cone which are in the upper part of the stillforming the inner walls of said upper part, whereby said Walls formcondensing surfaces.

2. A water still comprising two parts one located above the other, atruncated cone supported within the lower part and dividing the sameinto a lower chamber for the water to be distllled, and an-upper annularchamber adapted to contain the distilled inclosing the structure Withinthe second part of the still, and an open pipe extending from the apexof said cone, said two truncated cones, said collars, andthe cone whichare in the upper part of the still forming the inner walls of" saidupper part, whereby said wallsfform condensing surfaces.

in testimony whereof I afiix my signature in presence of two Witnesses.
